Vaillant maximum output capacity testing

The 10kW minimum electrical power is around 1kW so you end up with a minimum heating power of around 4 kW at 0°C, higher when it’s warmer. You’d potentially see a lot more more cycling with the 10kW.

True but oversized vaillants seem to do well. Is an oversized Vaillant a problem?
